Initial Comment:
Hi.

I have a PHP app where I generate a PDF file, using jasperreports, and then mail this file to a subscriber. I get the file from the website using this code:

--
		$ch = curl_init($rsPR->fields("strURL"));
		$tmpfname = tempnam(sys_get_temp_dir(), "IPV");
		$fpOutput = fopen($tmpfname, "wb");
		curl_setopt($ch, CURLOPT_FILE, $fpOutput);
		curl_setopt($ch, CURLOPT_HEADER, 0);
		curl_exec($ch);
		curl_close($ch);
		fclose($fpOutput);
		echo "filesize: $tmpfname: " . filesize($tmpfname) . "\n";
--
The file, at this point, has a multiple of 16Kbytes inside. The last bytes of the file are not there.
I changed to:
--
		$tmpfname = tempnam(sys_get_temp_dir(), "IPV");
		$fpOutput = fopen($tmpfname, "wb");
		$ch = curl_init($rsPR->fields("strURL"));
		curl_setopt($ch, CURLOPT_HEADER, 0);
		curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'read_body');
		curl_exec($ch);
		curl_close($ch);
		
		fclose($fpOutput);
		
		echo "filesize: $tmpfname: " . filesize($tmpfname) . "\n";
function read_body($ch, $string)
{
	global $fpOutput;
	
    $length = strlen($string);
    if (fwrite($fpOutput, $string) === FALSE) {
        echo "Cannot write to file";
        die();
    }
    return $length;
}
--
and the file is saved correctly.
This was not happening until I upgraded to PHP 5.2.10 from a previous version that I don't remember.
Hope you can find inside what is going on.
Best regards and thanks for a great piece of software.
